Hi Dustin,


This only happens when domU (guest) is running.  After shutting it down
the jerking/vibrating of mouse pointer stops.  I only allot 32M RAM to
each domU and there are 6 of them created.  In seldom occasion I run
all of them concurrently.  There are 4G RAM on board.  I think it has
more than sufficient RAM for dom0.  All domU are without GUI except
dom0 which runs GNOME desktop.


I suspect whether it would be the problem on Xen.  But I can't find out
the cause.  I don't know when it will happen.  The duration is short
then it becomes normal.
